Competitive Republican primaries for open seats in the 1st, 2nd and 3rd Districts, as well as those to win the right to challenge Schauer and Peters, have spurred aggressive fundraising and significant levels of borrowing. Thirteen non-incumbent Republicans have raised more than $100,000, and six have campaign debt of more than $100,000.

Among Democratic primaries, only the 13th District in Detroit shows signs of competitiveness. In the 13th District, incumbent Rep. Carolyn Cheeks Kilpatrick has raised $509,000 and holds $272,000 in cash on hand. Challengers John Broad and state Sen. Hansen Clarke have raised more than $100,000 each, but each has only a fraction of Kilpatrick’s cash balance.
